6 syslogd_selinux - Security Enhanced Linux Policy for the syslogd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the syslogd processes via flexible
11 mandatory access control.
12
13 The syslogd processes execute with the syslogd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep syslogd_t
20
21
22
24 The syslogd_t SELinux type can be entered via the syslogd_exec_t file
25 type.
26
27 The default entrypoint paths for the syslogd_t domain are the follow‐
28 ing:
29
30 /sbin/syslogd, /sbin/minilogd, /sbin/rsyslogd, /sbin/syslog-ng,
31 /usr/sbin/metalog, /usr/sbin/syslogd, /usr/sbin/minilogd,
32 /usr/sbin/rsyslogd, /usr/sbin/syslog-ng, /usr/lib/systemd/systemd-jour‐
33 nald, /usr/lib/systemd/systemd-kmsg-syslogd
34
36 SELinux defines process types (domains) for each process running on the
37 system
38
39 You can see the context of a process using the -Z option to ps
40
41 Policy governs the access confined processes have to files. SELinux
42 syslogd policy is very flexible allowing users to setup their syslogd
43 processes in as secure a method as possible.
44
45 The following process types are defined for syslogd:
46
47 syslogd_t
48
49 Note: semanage permissive -a syslogd_t can be used to make the process
50 type syslogd_t permissive. SELinux does not deny access to permissive
51 process types, but the AVC (SELinux denials) messages are still gener‐
52 ated.
53
54
56 SELinux policy is customizable based on least access required. syslogd
57 policy is extremely flexible and has several booleans that allow you to
58 manipulate the policy and run syslogd with the tightest access possi‐
59 ble.
60
61
62
63 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65
66 setsebool -P fips_mode 1
67
68
69
70 If you want to allow confined applications to run with kerberos, you
71 must turn on the kerberos_enabled boolean. Disabled by default.
72
73 setsebool -P kerberos_enabled 1
74
75
76
77 If you want to allow syslogd daemon to send mail, you must turn on the
78 logging_syslogd_can_sendmail boolean. Disabled by default.
79
80 setsebool -P logging_syslogd_can_sendmail 1
81
82
83
84 If you want to allow syslogd the ability to call nagios plugins. It is
85 turned on by omprog rsyslog plugin, you must turn on the logging_sys‐
86 logd_run_nagios_plugins boolean. Disabled by default.
87
88 setsebool -P logging_syslogd_run_nagios_plugins 1
89
90
91
92 If you want to allow syslogd the ability to read/write terminals, you
93 must turn on the logging_syslogd_use_tty boolean. Enabled by default.
94
95 setsebool -P logging_syslogd_use_tty 1
96

100 SELinux defines port types to represent TCP and UDP ports.
101
102 You can see the types associated with a port by using the following
103 command:
104
105 semanage port -l
106
107
108 Policy governs the access confined processes have to these ports.
109 SELinux syslogd policy is very flexible allowing users to setup their
110 syslogd processes in as secure a method as possible.
111
112 The following port types are defined for syslogd:
113
114
115 syslog_tls_port_t
116
117
118
119 Default Defined Ports:
120 tcp 6514,10514
121 udp 6514,10514
122
123
124 syslogd_port_t
125
126
127
128 Default Defined Ports:
129 tcp 601,20514
130 udp 514,601,20514
131
133 The SELinux process type syslogd_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

207 SELinux requires files to have an extended attribute to define the file
208 type.
209
210 You can see the context of a file using the -Z option to ls
211
212 Policy governs the access confined processes have to these files.
213 SELinux syslogd policy is very flexible allowing users to setup their
214 syslogd processes in as secure a method as possible.
215
216 EQUIVALENCE DIRECTORIES
217
218
219 syslogd policy stores data with multiple different file context types
220 under the /var/lib/syslog-ng directory. If you would like to store the
221 data in a different directory you can use the semanage command to cre‐
222 ate an equivalence mapping. If you wanted to store this data under the
223 /srv directory you would execute the following command:
224
225 semanage fcontext -a -e /var/lib/syslog-ng /srv/syslog-ng
226 restorecon -R -v /srv/syslog-ng
227
228 syslogd policy stores data with multiple different file context types
229 under the /var/run/syslog-ng directory. If you would like to store the
230 data in a different directory you can use the semanage command to cre‐
231 ate an equivalence mapping. If you wanted to store this data under the
232 /srv directory you would execute the following command:
233
234 semanage fcontext -a -e /var/run/syslog-ng /srv/syslog-ng
235 restorecon -R -v /srv/syslog-ng
236
237 STANDARD FILE CONTEXT
238
239 SELinux defines the file context types for the syslogd, if you wanted
240 to store files with these types in a diffent paths, you need to execute
241 the semanage command to sepecify alternate labeling and then use
242 restorecon to put the labels on disk.
243
244 semanage fcontext -a -t syslogd_unit_file_t '/srv/mysyslogd_con‐
245 tent(/.*)?'
246 restorecon -R -v /srv/mysyslogd_content
247
248 Note: SELinux often uses regular expressions to specify labels that
249 match multiple files.
250
251 The following file types are defined for syslogd:
252
253
254
255 syslogd_exec_t
256
257 - Set files with the syslogd_exec_t type, if you want to transition an
258 executable to the syslogd_t domain.
259
260
261 Paths:
262 /sbin/syslogd, /sbin/minilogd, /sbin/rsyslogd, /sbin/syslog-ng,
263 /usr/sbin/metalog, /usr/sbin/syslogd, /usr/sbin/minilogd,
264 /usr/sbin/rsyslogd, /usr/sbin/syslog-ng, /usr/lib/systemd/systemd-
265 journald, /usr/lib/systemd/systemd-kmsg-syslogd
266
267
268 syslogd_initrc_exec_t
269
270 - Set files with the syslogd_initrc_exec_t type, if you want to transi‐
271 tion an executable to the syslogd_initrc_t domain.
272
273
274
275 syslogd_tmp_t
276
277 - Set files with the syslogd_tmp_t type, if you want to store syslogd
278 temporary files in the /tmp directories.
279
280
281
282 syslogd_tmpfs_t
283
284 - Set files with the syslogd_tmpfs_t type, if you want to store syslogd
285 files on a tmpfs file system.
286
287
288
289 syslogd_unit_file_t
290
291 - Set files with the syslogd_unit_file_t type, if you want to treat the
292 files as syslogd unit content.
293
294
295
296 syslogd_var_lib_t
297
298 - Set files with the syslogd_var_lib_t type, if you want to store the
299 syslogd files under the /var/lib directory.
300
301
302 Paths:
303 /var/lib/r?syslog(/.*)?, /var/lib/syslog-ng(/.*)?, /var/lib/sys‐
304 log-ng.persist, /var/lib/misc/syslog-ng.persist-?
305
306
307 syslogd_var_run_t
308
309 - Set files with the syslogd_var_run_t type, if you want to store the
310 syslogd files under the /run or /var/run directory.
311
312
313 Paths:
314 /var/run/log(/.*)?, /var/run/syslog-ng.ctl, /var/run/syslog-
315 ng(/.*)?, /var/run/systemd/journal(/.*)?, /var/run/metalog.pid,
316 /var/run/syslogd.pid
317
318
319 Note: File context can be temporarily modified with the chcon command.
320 If you want to permanently change the file context you need to use the
321 semanage fcontext command. This will modify the SELinux labeling data‐
322 base. You will need to use restorecon to apply the labels.
323
324
326 semanage fcontext can also be used to manipulate default file context
327 mappings.
328
329 semanage permissive can also be used to manipulate whether or not a
330 process type is permissive.
331
332 semanage module can also be used to enable/disable/install/remove pol‐
333 icy modules.
334
335 semanage port can also be used to manipulate the port definitions
336
337 semanage boolean can also be used to manipulate the booleans
338
339
340 system-config-selinux is a GUI tool available to customize SELinux pol‐
341 icy settings.
